I can only think of a few reasons why you're having problems:
1) User error. You pressed a button or clicked something without even checking to see what you're doing.
2) You've been infected by viruses and spyware thanks to IE's wide-open backdoor into your OS.
3) Your firewall, anti-virus, or anti-spyware shield program is blocking you.
4) You've got parental controls/programs blocking you.
EDIT - Is it me or does this thread look messed up on the default skin here? Maybe it's just a temp hiccup...
